Y Y CARRIAGE-CURTAIN WINDOW ERAME.

TouallfwhomV may-concern.' I Be it known thatI, LAwRENoE 0.NELSON,

a citizen of thefUnited'v States," residing in the city `Of'Chicago,`-in the"county of Cook y"and State of Illinois, have 'invented certain 'new anduseful Improvements in Carriage- Curtain Window Frames, ofwhich'lthe fol- 'tain fabric between the vframe members. It

consists in the elements and features of construction shown and described, as indicated Figurel is -an elevation view of a carrlagecurtam window with the carriage curtainfabric partly broken away and one member of the window'frame partly'broken out to disclose interior details.'

Figure 2 is a section on a magnified scale at the line, 2-2, on Figure l.

Figure 3 is a section on a magnified scale at the line, 3 3, on Figure l.

Figure t is a magnied view of a section at the curved line, H, on Figure 1, de-

veloped into a plane.

Figure 5 is a plan view of a fabric-engaging clip in a modified form resulting from combining in one piece a corner clip and a side clip.

In the structure shown in the drawings the carriage curtain is shown double, consisting of inner and outer fabrics, A, A, which enfold the inner and outer frame members, B, B, respectively, the said fabric sheets having apertures for the windows out in them considerably smaller than the openings in the frames, so that the marginal por tions around the apertures of the fabrics are folded through the frame openings and back outwardly between the frame members, as clearly seen in Figures 2 and 3. The frame members, B, B, are rabbeted at their inner margins, as seen at l), to accommodate rubber gaskets, D, D, and the margin of the glass, F. The rubber gaskets are desirably originally in the form of rubber tubing as indicated in dotted line in Fig. 2, having a limited bore or axial cavity Appucauonmea may 8,1922. serial Nd, 559,14a g for increasing their yieldingness under the compression to which they are subjected in clamping'the frame members together upon the glass; so that these gaskets are distorted 'as seen 'in the crosssectional views, Figures 2 and '3, 1n the compression of the fabric and the frame together, and are spread out .into the otherwise unoccupied space of the vrabbet, appearingjin different form at different parts, according to the space which varies/somewhat by reason of being provided for' the fabric-engaging clips, as hereinafter described. y

f Thecharacteristic of the present invention consists in these clips for engaging the fabric and the manner ofplacing the same for that purpose, as will now be described.

rThe corners of the frame being rounded as shown in the drawings, the margin ofthe @fabric which islfolded back as described, .between the frame members for engagement is slitted radially with respect to the curve of the yrounded corner, the slits reducing the fabric at this pointto radially projecting ngers, a, a, as seen in Figure 1. In the outer marginal area Of the abutting faces of the frame members, B, B, beyond the rabbets, there are formed at the rounded corners seats for arcuate clip members, Gr, which have struck out from them clip fingers, g, with which the radial fabric fingers, a, are enga-ged; so that when the two frame members are clamped together, the fabric lingers are clinched in the apertures from which the*4 clip fingers are struck, seen in section in Figure 2. At other points along the straight sides and ends of the frame there are formed in the marginal areas of the abutting faces outside the rabbet, seats for small clips, H, which are angle-shaped in their Original formation having the finger, 7L, projecting at right angles to the plane of said abutting faces in which the clips are seated, and the fabric is slitted for insertion of these clip fingers through the slits, the lingers being then clinched down upon the fabric as seen in Figure 3. The slitting of the fabric to cause these lingers may then be done by the clip fingers themselves, the fabric being drawn around the frame to proper position and pressed down upon the 11p-standing clip fingers.

The frame members, B, B, are designed to be made by die casting, and in the process of casting there are formed in .theseats for the-clips, G and H, respectively, and pro jections, b2, for engaging apertures, gian@ it?, in ,the vclips respectively, ,the proj ections,
